Mike, Using the '61 mounts, the engine should go in fine. There is a difference in the oil pan, pretty sure that needs to be changed to the earlier style. I think you're going to have trouble with the transmission. There's no way I know of to convert it to pushbutton shift. Easiest way out would be to use a '62 transmission. You might think of upgrading the rear brakes to Bendix at the same time, they have a provision for eBrake. That would allow a '63 or '64 transmission by some minor fabricating of eBrake cables and brackets. I'm sure John & Don will chime in as both their G's have (or had) 440's in them. 300ly Russ Vaughan "Vath, Michael J." <mjvath@xxxx> wrote: Good mornin' & happy Spring. I wondered if anyone had done a driveline swap in a '61 - dropping-in a later engine & trans combo? If so, are motor & trans mount locations the same in later 383/440 cars? I'd like to combine a '67 440 driveline with a 300G shell. Other than adapting the shifter mechanism & e-brake, is it a bolt-in application? Are there pre-fab kits available for joining the push-button shift? Many thanks.
